Saft frowned, following Rider's gaze out into the forest. Preparing herself for a possible fight in which case if it was just another servant Saft would have to keep out the way and give support from the sidelines, however if this servant's master had come along to spectate too then it would possibly mean she would have to fight too.

"B-But that's impossible! They shouldn't have been able to avoid those seals unless--"

It hadn't occurred to her that she might have been followed by another servant in spirit form, or that the servant could have materialised from wherever they wanted to.

Stupid move, Saft. stupid.
